GUN -SIGHT.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed January 18, 1910. Serial No. 538,648.

To all whom it may concern:

Be it known that I, CHARLES F. VVOLLEN- BERG, a citizen of the UnitedStates, residing at Irby, in the county of Lincoln, State ofWVashington, have invented certain new and useful Improvements inGun-Sights; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements in rear gun-sights and hasparticular reference to a device of that kind adapted to be adjustedvertically in order to conform to the distance of the object aimed atand adjustable laterally according to the velocity of the wind when thelatter is blowing at right-angles to the line of sight.

With the above and other objects in view as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims; it being understood that various changes inthe form, proportion, size and minor details of the device may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention.

In the accompanying drawings forming part of the specification :Figure 1is a perspective view of the device mounted upon the fragment of anordinary rifle barrel of octagonal contour. Fig. 2 is a plan view of thedevice. Fig. 3 is a rear end elevation. Fig. 4 is a similar View butshowing the device applied to a barrel of circular contour.

Similar numerals of reference are employed to designate correspondingparts throughout.

The elevator includes in its construction a base plate 5. This member ispreferably formed of a single piece of sheet metal of suitable lengthand when applied to an octagonal rifle barrel as shown in Fig. 1, itsopposite longitudinal side portions are bent obliquely, whereby it willbe permitted to bear on three sides of the barrel. The base plate 5however, may be of arcuate contour, as shown in Fig. 4, so that it maybe readily applied to a rifle barrel of circular contour. Rising fromthe opposite longitudinal sides of the base plate 5 are a pair ofvertical side walls 6 and 7 the upper edges of which are inclinedrearwardly from a point at approximately the middle of each wall, thesaid upper edges being stepped as shown at 8 and 9.

The spring shank to which the sight proper is secured is designated bythe numeral 10. This member is preferably formed of a single piece ofspring steel and is provided adjacent to one end portion and on itslower face with a dovetailed tongue 11, extending transverse the shankand which fits into a transversely disposed dovetailed recess 12, formedin the upper face of the barrel 13. The rear or free end of the shank 10is provided with a pair of lateral lugs 14 and 15, which are designed toengage with the steps 8 and 9.

From the foregoing it is evident, it being understood that the shank 10is considerably less in width than the distance between the inner faceof the side walls 6 and 7 and the distance between the ends of the lugs14 and 15 corresponding to the distance between the steps 8 and 9, whenthe parts are positioned as shown in Fig. 1, by moving the elevatorforwardly will lower the rear end of the shank to the lower-most stepwhich will be the position of the parts when objects aimed at arecomparatively near; when ob jects relatively distant are aimed at thefree end of the shank 10 may be raised and held in raised position, byfirst moving the said free end upwardly and thence sliding the elevatorrearwardly until the lugs 14 and 15 engage with the steps to hold thefree end of the shank at the desired elevation.

The sight proper consists of a finger portion 16. This member ispreferably formed of a single piece of spring steel, considerably lessin width and somewhat less in length than the shank 10. The finger 16 ispivoted as shown at 17 to the shank 10, and at a point adjacent to therear or free end of the latter. The opposite or forward end of thefinger terminates in a spherical head 18, which points to a graduatedscale 19, formed on the upper face and adjacent the secured or forwardend of the shank 10. The scale 19 is laid off in degrees which show theangular distance that must exist between the central line of the barreland middle of the sight body when the wind is blowing a certain numberof miles per hour and in a direction at right-angles to the line ofsight,

The opposite end of the finger 16 is provided with a sight body 20,rising from the upper face of the finger and having its upper edgescurved and centrally provided with the usual notch 21, the center ofwhich is to be brought into alinement with the forward sight (notshown).

From the foregoing it can be seen that I have provided a device which isexceedingly simple in structure and comparatively inexpensive tomanufacture, embodying few parts and these so arranged that the dangerof derangement will be reduced to a minimum.

What is claimedhas new, is :d 1

1. In a n -sig t a ste e e eyato r, a spring sha n lr havingfitbh e endoppositely extending lugs to engage the steps of said elevator andprovided adjacent its opposite end with a degree scale, a finger ivotedto said Shani; having one end over-lying the aiinitfipgosffiasnd"previewm 2. In n-sight, the combination with a barrel; of a stepped elevatorslidingly fitted on said barrel, a spring shank secured at one end tothe barrel and provided at its opposite end with a pair of lateral lugsto engage with the steps of said elevator and further provided on itsupper face and at its secured end with a degree scale, a hand pivoted tothe shank having one end extending to a point adjacent the degree scaleand its 0pposite end provided with a sight body.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
